Synovial chondromatosis commonly occurs in the anterior compartment of the knee joint, predominantly in middle-aged men. It is relatively unusual in female children and is rarely encountered in the synovium beneath the meniscus. The present report describes a rare case of synovial chondromatosis that developed in the synovium just inferior to both menisci of the right knee in a 10-year-old girl. At this unusual age and location, there is a greater probability of missed diagnosis, due to the lack of definite informative incidence, and difficulty in finding the lesions during arthroscopic examinations. In the present case, multiple loose bodies were hidden by the meniscus, and thus, there were no structural abnormalities in the initial arthroscopic views before probing the meniscus. After careful inspection, we found numerous cartilaginous loose bodies and removed them as much as possible with arthroscopy.
滑膜软骨瘤病常见于膝关节前侧间室,主要发生于中年男性。在女童中相对少见,在半月板下方的滑膜中则更为罕见。本报告描述了一例罕见的滑膜软骨瘤病病例,发生在一名10岁女孩右膝双侧半月板下方的滑膜中。在这个不寻常的年龄和位置,由于缺乏确切的发病率信息以及在关节镜检查中难以发现病变,漏诊的可能性更大。在本病例中,多个游离体被半月板遮挡,因此在探查半月板之前的初始关节镜视野中没有结构异常。经过仔细检查,我们发现了大量软骨游离体,并在关节镜下尽可能多地将其取出。
